The connection to host on port 465 failed.

I am suddenly getting no outgoing mail on my Mac Mail application through my domain account.  The error message is "The connection to host (**Domain Mail Server**) on port 465 failed."  My domain host service provider went through all SMTP servers and ports that should work and have worked in the past.  ATT first level tech service was of no help and sent me to the pay Connect Tech service.  I had a similar problem a could of months ago with the incoming servers and it turned out to be an ATT problem.  I think it is again, so don't want to pay and don't think I should.  I just want to verify the correct settings.  Why should that be a pay service?

 

Isn't port 465 correct?  Isn't SSL enabled best?

@ccochran321 See this website to show correct set-up by email client:

Otherwise could just forward all ATT/Yahoo mail to a gmail account and use your Mac Mail client there.  Avoiding all these ATT/Yahoo problems that constantly crop up. 😉

Except that I'm not trying to set up ATT email.  I don't use ATT email.  I use my own domain email.  Apparently ATT doesn't like that and refuses to help.

Did the technician at your e-mail provider suggest that you attempt to connect to his server using TELNET as a diagnostic tool?

 

TELNET

 

and see what kind of response you get.  You normally get a blank screen (which means you made a connection) at which you can try entering a few character and pressing ENTER (you would get a banner and an error message from most SMTP hosts that don't require SSL at this point).  This is a successful test.

 

If it returns to the command prompt as soon as you type a few characters (before you hit ENTER) without a message, it probably means SSL is required.  But you still made a connection.

 

If you get a message that the connection couldn't be made, then you have a connection problem somewhere between your PC and the mail server.  Could be AT&T, could be you, could be the far end.  Very hard to tell.  If you get either of the first two, then it appears that your connection is okay and that your log in is being denied at the mail server.
